The normal value of blood ammonia is 18-72 μmol/L. Blood ammonia of 106 umol/L is not serious if it is elevated for physiological reasons, but it is more serious if it is elevated for pathological reasons (cirrhosis of the liver, intestinal injuries, kidney failure, etc.).

This situation is not serious, change the diet, after resting, generally can be restored to normal. 2.
